Former New Groove of the Month and 30 Rock guest star Robert Randolph opened for Dave Matthews Band at Camden, NJ’s Susquehanna Bank Center this past Saturday and Sunday with his Family Band. As he has on occasion, Randolph later took the stage with the evening headliners, playing pedal steel on a version of “Rhyme & Reason” Sunday night. Randolph recently sat in with the group at San Francisco’s Outside Lands festival as well. Both Randolph and Matthews will perform in Scranton, PA this Wednesday.
